To all whom it may concern Be'it known that I, J os'ErH BUHR, a citizen of the United States, and a resident of I the city of Norwood,in the county'ofI-Iamilton and State of Ohio, have inventedcertain new and useful ImprovementsinflCon had to the accompanying drawings,tforming part of this specification.

My invention relates to condensers, partic'ularly of the wate njacketed coil type, wherein the gases to be condensed are passed through a coil, in a vessel through which a stream of cold water is pumped. It has special relation to condensers for use in the distilling of gasolene in processes wherein a dirty oil is refined by distillation. In such processes there is a supply of cold dirty oils which must be heated, and it is designed by my condenser to use these cold oils in condensation, and at the same time heat them.

preparatory to entering the still, as well as givingthem a preparatory cleaning.

The designed object is accomplished by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed, whereby the oil to be heated is passed over baflie plates in a compartment of the condensing vessel for the vaporized oils.

In the drawings,

Figure 1 is a central vertical section of the condenser.

Fig. 2 is a top plan view thereof.

Fig. 3 is a horizontal section thereof.

In condensers of the type generally used today, wherein the water-jacketed coil is employed in gasolene distillation, it is necessary to pump through the vessel about six gallons of water for each gallon of gasolene distilled. It is designed by my improved condenser to so utilize the inflowing cold oils for the still that the necessary water,

same time the oil to be distilled will be heat- Specification of Letters IPatent: I I

The coil 'has a radius of a little morethan half thesize ofthe radius of the vessel, and a space-1s left inside'the coil, downthe' center of the vessel, for the auxiliary cooler" through which the cold oils are to pass;

A narrow cylindrical vessel or' compart-.

top 12ofthe vessel Q -ha'sopenings for the entrance of the inlet pipe 13 at the center thereof, and the outlet pipe 1 1 at the'side thereof. The inlet pipe 13 extends substantially theentirelength of the vessel 9, opening at the bottom, and has-mounted on it a series of bafiie plates 15, 15.

The baffle plates are of nearly the same diameter as the vessel 9 and are made convex in shape fora purpose to be described.

It is preferred to mount these bafiie plates on the pipe by means of locking nuts 16, 16,

screwed onto the pipe. a The. operation of the condenser is as follows. The hot gases-from the still flow into the cooling coil 6 at the top of'the main vessel and out at the bottom. The cold water supply is introduced at 1, passes through the vessel and escapes at 5 from the top thereof. The cold oils enter the compart: ment 9 at the top and flow to the bottom thereof through the pipe 13. At the bottom they emerge and flow up this chamber, being continually forced to the sides and caused to circulate by the baflie plates so that all of the oil comes into asclose contact as possible with the water in the cooler. The function of the cold oil is to take heat out of the water so that less water is necessary to condense a given amount of gasolene gas, and this heat taken out warms up the cold oil so that when it flows out of the inner vessel at 14 to the still it will take less heat to distil when it is in turn to be distilled.

, The cold oils being dirty will in flowing over the bafile plates deposit a certain amount of sediment on the upper surface of these plates, and they being convex will be easily washed off and cleaned by an occasional flushing. When the condenser is first filled with cold water, it will be understood that a sufliciently low temperature will be obtained, not to require for an hour or so any additional supply of cold water.

' By referring to specific shape'of parts or T other mere details of design it is not desired to limit the claims that follow, as it is desired in the claims to cover all equivalent structures Whenever general terms are used. It IS believed that the structure of the con to mention such modifications as Would present themselves to the ordinary mechanic at any particular 'point of installation.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent, is r coil, said chamber being adapted to receive liquids, and baflles in the chamber for serv- "posedescribed. denser isnow adequately described and its operation noted and that it is not necessary "2.
